Abstract
750,749. Folding paper ; sheet delivery apparatus. GOSS PRINTING PRESS CO. May 14, 1954 [June 15, 1953], No. 14213/54. Class 100 (1). A sheet-folding mechanism is supported for movement between first and second positions, whereby folded products may be discharged in first or second directions, there being a delivery device for receiving the products from the folding mechanism when the latter is in its first position and which is supported for movement between a first position adjacent the folding mechanism and a second in a remote position, the delivery device and folding mechanism being conjointly movable between the two positions. As shown, the apparatus comprises a former 20 (Fig. 1) adapted to produce a lengthwise initial fold on a printed web W, the web W then passing between nip rollers 22 and web drawing rollers 23 journalled in mainframes 24 (Fig. 3). The folded web is then cut between a cutting cylinder 28 having a transverse cutting blade 32, and a rotary blade folding cylinder 30 having folding blades 38 adapted to feed a severed product to the nip of folding rollers 40. The arrangement is such that the product P may be given each two or three folds. To this end the cylinder 28 and rollers 40 are carried in swing frames 42 for movement about the centre of the cylinder 30 so as to change the direction in which the twice folded product P is discharged, the swing frames having a forked construction so as to straddle depending arms of the members 24 in which the shaft 46 of the cylinder 30 is journalled. Mounted in the depending arms of the members 24 are pinions 64 meshing with gear segments 62 formed on the inner forks of the swing frame 42. For locating the swing frame 42 in either position apertured lugs 72 are provided engageable with either of two pads 74, 75 formed on the frames 24, and through which screws 76 may be inserted and threaded into the pads. When it is desired to make two folds in the products P the cylinders 28, 30 and rollers 40 are adjusted to the position shown in Fig. 1, and the products P are discharged into a rotary S-fly 84 for delivery on to a conveyer 124. The S-fly 84 is mounted on a swing frame 92 pivoted on a shaft 94 and is driven through gears 96, 98 and 100, the latter being loosely mounted on the shaft 94 and suitably driven from the drive for the cylinders 28 and 30. The swing frames 42 and 92 are joined together by links 106, a lost-motion connection, comprising a slot 108, shaft 110, and stop screw 114, being provided between the links 104 and the swing frame 92. Thus, when the swing frame 42 is moved anti-clockwise from the position shown in Fig. 6 to that shown in Fig. 1 the swing frame 92 is rotated about the shaft 94 and the S-fly drawn up so as to be positioned immediately below the rollers 40 to receive twice folded products therefrom. When it is desired to make three folds in the products P, the cylinders 28, 30 and rollers 40 are adjusted to the position shown in Figs. 2, 3 and 6, the S-fly 84 being lowered into the inoperate position shown in Fig. 6. After the second fold the products are discharged from the rollers 40 to pulleys 130, 132 which advance the products on to a slotted table 134. Above the table 134 is a folding cylinder 138 having a folding blade 140 adapted to fold the products through the slot to folding rollers 142 beneath which is an S-fly 144 which delivers the products on to a conveyer 146.
